I don't think that it's normal for a Bitcoin investor to be emotional about his or her holdings, unless you are investing with an amount you can't do away with, but if you are investing with an amount you can afford to lose, bro nothing is making you emotional about your holdings
All investors are human, not robots or bots so human all have emotions and everyone is affected by human emotions. Difference is between people who can be more or less disciplined than others and have better or worse risk and capital management.
Those things are either well controlled or bad controlled that will decide those people reactions on a same market. You can have positive or negative emotion and feelings about the market but if you manage risk and capital well enough, and if you are disciplined enough, you will not either do FOMO purchase or panic sale. Because almost everything you do with your investment portfolio and decisions of purchases and sales are done very disciplined and less likely emotional affected.
That is why we must learn how to control our emotion so when we become an investor, we will not get the market affect. We can still calm down especially when the price fall but we can see a chance to buy back to add more amount. But if we don't learn anything, that will be a matter of time for us to lose our emotion control.
Having emotion control will also help you to prevent panicking when something goes wrong. You can adapt with the current situation without emotional because you are ready with that. With emotion control, you can run your investment without worry and still follow the plan.
